// Step 1. Initialize System Control:
// PLL, WatchDog, enable Peripheral Clocks
// This example function is found in the DSP2833x_SysCtrl.c file.
InitSysCtrl();
// Step 2. Initalize GPIO:
// This example function is found in the DSP2833x_Gpio.c file and
// illustrates how to set the GPIO to it's default state.
// InitGpio(); // Skipped for this example
InitXintf16Gpio(); //zq
// Step 3. Clear all interrupts and initialize PIE vector table:
// Disable CPU interrupts
DINT;
// Initialize the PIE control registers to their default state.
// The default state is all PIE interrupts disabled and flags
// are cleared.
// This function is found in the DSP2833x_PieCtrl.c file.
InitPieCtrl();
// Disable CPU interrupts and clear all CPU interrupt flags:
IER = 0x0000;
IFR = 0x0000;
// Initialize the PIE vector table with pointers to the shell Interrupt
// Service Routines (ISR).
// This will populate the entire table, even if the interrupt
// is not used in this example. This is useful for debug purposes.
// The shell ISR routines are found in DSP2833x_DefaultIsr.c.
// This function is found in DSP2833x_PieVect.c.

// Enable global Interrupts and higher priority real-time debug events:
EINT; // Enable Global interrupt INTM
ERTM; // Enable Global realtime interrupt DBGM
// Interrupts that are used in this example are re-mapped to
// ISR functions found within this file.
// Step 4. Initialize the Device Peripheral. This function can be
// found in DSP2833x_CpuTimers.c
// InitCpuTimers(); // For this example, only initialize the Cpu Timers
// Configure CPU-Timer 0, 1, and 2 to interrupt every second:
// 150MHz CPU Freq, 1 second Period (in uSeconds)
//ConfigCpuTimer(&CpuTimer0, 150, 1000000);
//ConfigCpuTimer(&CpuTimer1, 150, 1000000);
//ConfigCpuTimer(&CpuTimer2, 150, 1000000);
// StartCpuTimer0();
// EPwmSetup();
